How an eSIM works in Singapore
An eSIM is a digital SIM card built into your phone. You purchase a data plan through an app, install it over Wi-Fi before you travel, then activate it when you land. Your original SIM stays in the phone for calls and texts on your home number, while the eSIM handles mobile data in Singapore.
- Download the eSIM app and buy a Singapore data plan that fits your trip length and usage.
- Install the eSIM profile by scanning the QR code over Wi-Fi before your flight - the process takes a couple of minutes.
- When you arrive in Singapore, turn on data roaming for the eSIM line and select it as your primary data source in settings.
- Top up with more data directly in the app if you run out during your stay.
Coverage and networks in Singapore
The provider's Singapore eSIM connects to Starhub and Singtel, two of the island's main mobile operators. Both run modern 3G, LTE and 5G networks with strong coverage across the city-state.
| Operator | Technology | Where it is strongest |
|---|---|---|
| Starhub | 3G / LTE / 5G | Central Business District, Marina Bay, Orchard Road, Sentosa, Changi Airport, residential estates |
| Singtel | 3G / LTE / 5G | Downtown Core, tourist areas, Jurong, Woodlands, underground MRT stations, most public spaces |
Singapore is a compact city-state with dense infrastructure. You'll find signal strength consistently high across the entire island, including underground train stations and shopping malls. 5G access depends on your phone's capability and the specific plan you choose - check the plan page for details on speed tiers and any fair-use policies.
Which plan for which trip
Match your data plan to how long you're staying and what you'll do. A short city break needs less than a month-long work trip.
| Trip type | Days | Typical usage | Suggested data |
|---|---|---|---|
| Weekend city break | 2-3 | Maps, messaging, social media, restaurant searches | 2-3 GB |
| One week | 7 | Navigation, photo uploads, video calls, occasional streaming | 5-7 GB |
| Two weeks | 14 | Regular browsing, remote work, streaming music, daily video calls | 10-15 GB |
| Month | 30 | Full remote work setup, video conferencing, streaming services, heavy app use | 25-30 GB or unlimited daily |
Plans start from $0.92 per GB for fixed allowances. For longer stays or heavy users, the provider also offers unlimited daily plans from $1.90 per day - useful if you don't want to track consumption.
eSIM vs a local SIM card in Singapore
You can buy a local prepaid SIM at Changi Airport kiosks or mobile operator stores in town. Registration requires your passport, and staff usually speak English. The process takes ten to twenty minutes if there's no queue. An eSIM saves that time and lets you land with data already configured - you just toggle a switch in settings.
Setup time
eSIM installed at home before departure; local SIM means finding a shop, queuing, and waiting for activation.
Cost comparison
Local SIMs offer competitive rates if you buy large bundles; eSIM pricing becomes more convenient for shorter trips when you factor in travel time to a store.
Flexibility
Top up an eSIM instantly in the app; local SIM top-ups require finding a retailer or using a local payment app.
Multi-country travel
If you're visiting Thailand or Malaysia after Singapore, a regional eSIM works across borders; a local SIM stops at the border.

Phone compatibility and setup before you fly
Check these points before you buy an eSIM plan:
- Your phone must be unlocked - carrier-locked devices won't accept a second profile.
- The device must support eSIM technology; most iPhones from XS onward and recent Android flagships do.
- Install the eSIM over Wi-Fi at home, not at the airport gate.
- Save a screenshot of the QR code or keep the email handy in case you need to reinstall.
- Label the eSIM line clearly in your phone's settings so you know which SIM handles data and which handles calls.
Our eSIM-compatible phones list covers hundreds of models with step-by-step setup guides for iOS and Android.
Staying connected in Singapore: practical tips
Singapore has no major internet restrictions - you can use WhatsApp, Google services, and social media without a VPN. The MRT trains have signal in most tunnels, but download offline maps for Google Maps or Maps.me as a backup when you're deep underground or in older stations on the East-West line.
Bring a power bank. Using navigation and mobile hotspot drains your battery faster, especially if you're walking around Gardens by the Bay or Sentosa in the heat. Singapore uses Type G plugs (three rectangular pins), the same as the UK; if your charger doesn't fit, you'll find adapters in any convenience store.
Most tourist areas, shopping malls, and cafes offer free Wi-Fi, but it usually requires registration with a phone number or email. An eSIM means you don't have to hunt for Wi-Fi passwords when you need directions quickly. If you run into connection issues, our eSIM troubleshooting guide walks through the common fixes.
Other destinations in Southeast Asia
If Singapore is one stop on a longer Southeast Asia trip, consider a regional eSIM that covers multiple countries. The Southeast Asia eSIM works in Thailand, Vietnam, Indonesia, Malaysia, Cambodia, Brunei, and Singapore on a single plan. You pay once, install once, and data roams across borders without buying separate country plans or swapping profiles.
Frequently asked questions
Do I need to pay a deposit or provide credit card details to activate the eSIM in Singapore?
No deposit is required. You pay for the data plan upfront in the app, install the eSIM profile, and it activates automatically when you connect to a local network in Singapore.
When does the validity period of my Singapore eSIM plan start counting down?
The plan's validity starts the moment your phone connects to a mobile network in Singapore for the first time. Installing the eSIM at home does not start the countdown.
Can I use my phone as a mobile hotspot to share data with other devices in Singapore?
Yes, hotspot functionality is supported. Check the plan page for any data-sharing limits or fair-use policies that might apply to tethering.
Will I be able to receive calls and texts on my regular phone number while using the eSIM in Singapore?
Yes. Your original SIM stays active for calls and texts on your home number. The eSIM provides only mobile data - you'll make voice calls through WhatsApp, FaceTime, or other internet-based apps.
Does the Singapore eSIM support 5G speeds, and will I automatically connect to 5G networks?
5G is available on both Starhub and Singtel networks. Your phone will connect to 5G if it supports the technology and the plan includes 5G access - check the plan details to confirm.
What should I do if my eSIM is not connecting to a network after I land in Singapore?
First, turn on data roaming for the eSIM line in your phone's settings. Restart the phone, then manually select Starhub or Singtel as your network operator. If the issue persists, visit our troubleshooting guide for step-by-step diagnostics.
